The right end of the first antenna 11 is coupled to the first electromagnetic wave signal to generate a second electromagnetic wave signal. The equivalent electrical length of the first antenna 11 is adjusted by the first tuning module 131 of the first antenna 11, so that the first antenna 11 radiates the second electromagnetic wave signal.

The antenna performance of small wireless products is improved by adopting a slot-coupled antenna form; the antenna and the main feed antenna are configured on the main board to be coupled so as to optimize the antenna performance of the small-size product, reduce the influence of human body on the antenna performance and enhance the communication function. The antenna performance of the small wireless product is improved in the form of an antenna with the length of the main ground extended by the intelligent tuning module; for small-sized wireless products, the normal antenna wiring area and the antenna height are limited, the main ground length can be intelligently increased through the wireless antenna system, and the main ground length is intelligently adjusted according to the real-time signal strength acquisition system of the products to increase the wireless performance of the products. The embodiment of the disclosure can adjust the main working length of the product in real time according to the radio frequency logic state of the system, thereby achieving the purpose of improving the performance of the whole antenna. The embodiment of the disclosure can actively adjust and prolong the grounding mode through the feedback of the communication module so as to achieve the optimal antenna resonance position, and improve the performance of the product antenna and the communication function of the whole machine.
